The Gambler Who Cracked the Horse-Racing Code

Across the road from Happy Valley, 27 floors up, two Americans sat in a plush office, ignoring a live feed of the action that played mutely on a TV screen. The only sound was the hum of a dozen computers. Bill Benter and an associate named Paul Coladonato had their eyes fixed on a bank of three monitors, which displayed a matrix of bets their algorithm had made on the race—51,381 in all.

Benter and Coladonato watched as a software script filtered out the losing bets, one at a time, until there were 36 lines left on the screens. Thirty-five of their bets had correctly called the finishers in two of the races, qualifying for a consolation prize. And one wager had correctly predicted all nine horses.

“F—,” Benter said. “We hit it.”

It wasn’t immediately clear how much they’d made, so the two Americans attempted some back-of-the-envelope math until the official dividend flashed on TV eight minutes later. Benter and Coladonato had won a jackpot of $16 million. Benter counted the zeros to make sure, then turned to his colleague.

“We can’t collect this—can we?” he asked. “It would be unsporting. We’d feel bad about ourselves.” Coladonato agreed they couldn’t. On a nearby table, pink betting slips were arranged in a tidy pile. The two men picked through them, isolating three slips that contained all 36 winning lines. They stared at the pieces of paper for a long time.

Then they posed, laughing, for a photo—two professional gamblers with the biggest prize of their careers, one they would never claim—and locked the tickets in a safe. No big deal, Benter figured. They could make it back, and more, over the rest of the racing season.
